I need to find a detailed trade magazine / journal for optical
components (i.e. amplifiers, pump lasers etc).  The larger and more
detailed the better.

IŽve found some magazines and other online sources that may be
interesting for you.

Optics InfoBase, which is the The Journal of the Optical Society of
America is
“devoted to developments in any field of classical optics, image
science, and vision. JOSA A includes original peer-reviewed papers on
such topics as atmospheric optics, image processing, scattering and
coherence theory, machine vision, statistical optics, diffraction and
gratings, color, clinical vision, and visual optics.”
Some examples of articles contained in the current issue:
“Effects of rod activity on color perception with light adaptation
   Bjorn Stabell, Ulf Stabell
   Contrast discrimination with pulse trains in pink noise
   G. B. Henning, C. M. Bird, F. A. Wichmann
   Contrast discrimination with sinusoidal gratings of different
spatial frequency
   C. M. Bird, G. B. Henning, F. A. Wichmann
   Tiptilt error for extremely large segmented telescopes: detailed
theoretical point-spread-function analysis and numerical simulation
results
   Natalia Yaitskova, Kjetil Dohlen
   Statistical-information-based performance criteria for
Richardson-Lucy image deblurring”
from:
( http://www.opticsinfobase.org/current.cfm?journal=1 )

Maybe this one focuses too much on science.
Anyway, youŽll find it at:
Optical InfoBase
( http://www.opticsinfobase.org/current.cfm?journal=1 )

Another interesting one could be the site of Spie - INTERNATIONAL
SOCIETY FOR OPTICAL ENGINEERING:
“ The Society was founded in 1955 to bring together engineers from
several technical disciplines involved in high-speed, optically based
test and measurement. Since then, the field of optical engineering has
evolved from a multidisciplinary amalgam of physics, electrical and
mechanical engineering, and materials science into an identifiable
discipline in its own right. Simultaneously, SPIE has grown into a
vital international organization that addresses virtually all
subfields associated with optics and photonics technologies and their
many engineering, scientific, and commercial applications.”

On their  big webpage youŽll find a lot of papers on the field of
optoelectronics and they publish the Optoelectronic Magazine OE:

The “Optical Networks Magazine is an international, peer-reviewed
magazine that gives you timely reports on the challenges and
opportunities driving the research, development, and commercialization
of optical communications technologies.“

Another certainly interesting one could be:
“ The Optical Society of America brings together optics and photonics
scientists, engineers, educators, technicians, and business leaders.
OSA's membership totals more than 14,000 individuals from over 70
countries. Approximately 32% of the Society's members reside outside
the United States. Officers of the Society are elected by the
membership.”

The Electronic Component News have some articles on Optoelectronics an
their site.
(http://www.e-insite.net/ecnmag/index.asp?layout=featuredProducts&industryId=19621&industryName=Optoelectronics+and+Displays&head=Optoelectronics+%26+Displays
)
Those asp-links sometimes make trouble. YouŽll find the main page at:

IŽm not sure if a German magazine can help. This one is especially
about lasers.
Grüttner Gruppe
( http://www.eurolaser.de/ )

The German Magazine “elektronikpraxis” has an english database on the
subject:
DEEP database
( http://www.elektronikpraxis.de/deep/index_en.shtml )

ACE Suppliers have a similar database you might wish to browse for
further info. The “magazine focuses on semiconductors,
components/parts, optoelectronic components, connectors, cables, and
switches around Asia”
from: 
ACE Suppliers
( http://www.acesuppliers.com/ )

The site of Optical manufacturing is ” providing technical information
to engineers who make optoelectronic and photonic components and
products. Covers device fabrication, assembly packaging, and
integration and test and measurement”
